Abandoned motorcycle chained to a tree

This motorcycle (number plate 27QAQ) has been sitting under a tree on the small path between Moana Rd and Waiapu Rd for at least two years.
It is chained to the tree and not in a designated parking space.
It is covered in spider webs so it obviously has been abandoned.
It is on council land where there is no public right of way for vehicles so it should be removed.
